Specification of Letters Patent.

CHICAGO, ILLINOIS, ASSIGNOR 0F ONE-HALF TO ALVIN W. BAKER, OF OAKLAND,CALIFORNIA.

PatentedMay 21, 1912.

Original application led November 17, 1910, Seria1 No.5592,917. Dividedand this application filed February 2, 1911. Serial No. 606,274.

To all whom it may concern:

Beit known that I, JAMES IV. RUMSEY, a citizen of the United States, andresident Vof Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Car-Doors, of which thefollowing is a -speciiicatiom and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to car doors, and has been divided out of mypending application for patent on car doors filed November 17th, 1910,serial No. 592,917.

The invention relates more specifically to means for guidedly supportingand retaining the lower edge of a sliding car door;V

vbracket-s, nevertheless when 'such brackets are used access to theinterior of the car `without sliding the door is frequently obtained.`by breaking oil' that portion of the bracket which overlaps the door,whereupon the lower part of the door may be swung away from the'car bodya sufficient distance to permit a person to enter the door opening. v

`The invention further contemplates that the door shall be guidedlysupported across its entire width, in order that-it may not be sprungout of shape by pressure of freight against any part of the door fromthe ins1 e.

` In the accompanying drawings Figure 1 is ya detail transversesectional view of a car body equipped with a door in the manner rovidedby the invention, the central Aportion of the door and car wall beingbroken away; Fig. 2 is a perspective view showing details of the insideface andV one edge of the car door; and Fig. 3 is a detailperspectiveView of the side wall of the car land door, some of the parts beingbroken away to show the internal construction.

Details of the side wall of a car are shown at 10. The car has the usualsidedoor opening 11, andthe door 12 slides over the opening. The upperedge of the door may be slidingly supported in any convenient manner. Asshown, a combined'door track and hood 13 extends over the top of thedoor opening 11. This combined door track and hood comprises a channeledplate having upper and lower horizontal webs 14, 15, and verticalmarginal flanges 16, 17.

The vertical flanges 16, 17, are secured to the car body by bolts 18,19. The lower horizontal web 15 of the combined track and hood islongitudinally slotted intermediate its ends, as indicated at 20, toreceive the upper edge of the door 12, and rollers 21, 22, are securedto the door to roll on the upper face of the web 15 at each side of theslot 20. l

In carrying out the invention a T rail 23 is secured to the side wall ofthe car below the door opening 11. This T rail preferably extendshorizontally along the side wall of the car a suliicient distance to beengaged by the door throughout its entire `width when the door is ineither its open or closed position. The inside face of the door 12 isl'horizontally slotted, as indicated at 24, to receive the head 25 ofthe T rail 23. To securely hold the door against the side of the carmetal bars 26, 27, are secured to the inside face of the door above andbelow the slot 24. The edges of these bars overlie the slot and arepreferably separated a less distance than the width of the T head 25 ofthe rail 23. made in the form of an angle having a horizontal flange 28which underlies the lower edge of the door for its entire'width, thusserving as a binding or protection for the lower edge of the door-whenthe latter is made of wood, asfshown. The T rail 23 is secured to thecar by bolts 29 passed through the flanges of the T rail and through theside wall 10 of the car. The

bars 26, 27, are secured to the door 12 by bolts 30 which are passedthrough the bars EISSi-EU The bar 27 is preferably v and through thedoor. If now the bolts 29 are so disposed that their heads 31 come uponthe inside of the side wall 10 of the car, and the bolts are so disposedthat their heads 32 come upon the outside of the car door 1Q,unauthorized removal of the bolts may be prevented by riveting over theends 33, 34E, of the bolts upon the nuts, as 35, 36, applied thereto.Preferably the nuts 35 and 36 are oountersunk in the flanges of the Trail 23 and in the bars 26, 27, respectively, to provide for a close fitof the door against the side Wall of the car. By the use of the T rail23 and bars 26, 27, a sliding bearing for the lower edge of the door isprovided across its entire width, and distortion of the door as bypressure of freight upon its inside tace is eiiectually prevented. Thenthe door l2 is made of Wood, as shown, the slot 24k is formed by gainingout the inside face of the door.

I claim as my invention l. In combination with a car body having a dooropening in a vertical Wall thereof, a door sliding over the opening infront of the plane of the said vertical Wall of the car body, the doorbeing larger than the opening and overlying` the said vertical Wall ofthe car below the opening, and continuous interealating T slot and Trail members, one of suoli members extending horizontally across theinside face of the door for its entire width and the other of suchmembers extending horizontally across the said ver- 'tical Wall of thecar below the door opening the T-slot member being countersunl in theface of the part across which it extends.

2. In combination with a car body having a door opening in a verticalWall thereof, a continuous T rail extending horizontally across the saidvertical wall ot' the car body below the door opening, a door slidingover the opening in front of the plane of the said vertical wall of thecar body, the door being larger than the opening and extend ing belowthe same for its entire Width, the said extended part of the door beingprovided with a continuous horizontally disposed T slot upon its insideface, said T slot being extended across the entire Width of the door andbeing engaged with the said T rail, the throat of the T slot being ofless Width than the head of the T rail and embracing the Web ofthe saidT rail behind the head, and means coveredby the door for securing the Trail to the said vertical Wall of the car body.
